LxW what would 8x10 be if u doubled it?

Question

To glass pieces from a frame if I glued the mm what would it be, both are 8x10

Answer 1

What does "IT" refer to?

 

8 times ten is 80; if you double that, you get 160.

 

If you double each of Length & Width, then area LW would change from 80 to 320.
